Salam o Alykum,FrontAccounting latest 2.3.16, installed on ubuntu-server 12.04 ip=192.168.1.101 1- printer is shared with LPR/LPD service on some Win7 machine ip=192.168.1.148, I told to Frontaccounting that printer is on 192.168.1.148 port 515, because FA support lpd printer at the moment, When FA is printing invoice Quotation or Reports, the prints is strnage, some garpage raw text or some .php or html coding,the images can be checked here2- Next I installed cups on my ubuntu-server machine and added that shared printer via cups to my ubuntu machine, Now I can send print from command prompt from the same ubuntu-server machine like

and the print is normal text printNow here i told to frontaccounting that printer is on localhost, Now if I am sending print from frontaccounting via browser,I am getting error on tail -f /var/log/cups/error.log
